Hello Again All,
I am in need of the A/C harness for a late '59 Plymouth. The difference between the early and late cars is that early cars had two speed blowers, late cars had three speed blowers. I need the following wires…
1.) Compressor Clutch to thermal switch
2.) Thermal Switch to push button control switch.
3.) Blower Motor to to T disconnect.
4.) T disconnect to blower switch
5.) Blower resistor to T disconnect
6. ) Blower resistor to push button control switch
I’m also in the market for the resistor itself. If you don’t have one to sell but have one, I would be more than happpy to pay a deposit to allow me to copy it. In addition, I would have a new harness to send back to you as a token of my appreciation. Any help would be appreciated. Thanks for your time.

I had a very difficult time findingg a/c parts for my car. Wasn’t it you who had a lead on a Texas a/c car? Ron Keij had found one being offered for parts, but then the guy changed his mind, or something to that effect.
Where is the resistor located (if I happen to have one on my car?)
Hey Roger,
I know it’s probably going to come down to making my own harness and fabricating what I need from my parts stashes. I just wish I could come up with a better solution/parts car. If you have the resistor, it will be mounted (sorry for lack of specification) somewhere under the dash on the metal frame as it needs to dissipate heat. If you have the three position blower switch, you should have one. If you have a two speed, it will not be there. I did have the lead on the Texas AC car years ago. I bought the car and basically had everything I wanted shipped to me. Unfortuantely, the A/C harness and wires were eaten by mice and had disintegrated. I managed to salvage a few wires but it’s not enough to make the puzzle complete. I have the A/C service manual which illustrates the wiring diagram but doesn’t show you the parts or locations. I did use the template you made me so many years ago and it worked like a champ! Any help would be appreciated.
Thanks,
Frank
I bought an a/c related item off ebay a few yrs ago.
It is a service instuction sheet, 33 1/3 record and film strip. I have never played the record or viewed the film strip. I wonder if it shows actual locations of things-
Then I also have a Canadian 1959 Shop Manual, which has some photos, small B/W shots, showing the layout of SOME things. I still can’t find the resistor you speak of.
Hey Roger,
Does your temperature control switch on the dash read Hi-Med-Low on the top or Hi-Lo? You may have the early two speed set up. Let me know. I still need to get the lengths and location of the thermal switch and its wires (the white wire from the dash switch to the thermal switch and the blue wire from the thermal switch to the compressor), the length of the blower motor wire to its first disconnect, and figure out where the resistor is, (maybe its inline with the harness but I thought it should be mounted to dissipate heat). Sorry for the late reply. I’ve been taking online college courses. Fun going back to school after 13 years. I needed a break!
Take Care,
Frank
Frnk, I will do my best to get you answers, but I think you’ll have better luck speaking with Fins59 in Wisconsin. (He has a factory-equipped A/C car).
Fins59 here - I had kind of a detailed post here and a minute ago this dang computer lost it and went back to main page, so will try again.
I have factory air in my '59 but it is non-working due to fact previous owner lost compressor, so I think I have everything except compressor.
When you say temp control switch I’m thinking you mean the push buttons. I have 5 buttons and the lever. Buttons read from top down “OFF” “MC” “FC” “DEF” and “H”. The “lever” says WARM on it, and has arrow pointing up.
There is a nice shiny knob attached to dash just below radio that says FLOOR AIR on it. I don;t know what this button does, if it turns or pulls out. Maybe it opens and closes fins on A/C unit under dash.
I have to get one of my boys over here to show me how to take and post pictures.
Frank, any questions, fire away.
One thing Frank wants to know is regarding the temperature control. THis is the arm with little ball on end which sticks out of the right side of teh pushbutton controls. Embossed into that little ball may be the words Lo-Med-Hi. The temperture is controlled by moving lever up or down. The speed of the blower fan is controlled by moving the lever out or in.

I have the 3-spd blower.
The thermostatic switch is mounted to the left side of the plenum opening..
Regarding wiring, I never got that completed. Maybe YnZ can give you more wire than needed, and a connector to terminate it when you (hopefully) figure it all out.
My camera got dropped and no longer takes close-up photos. Worse, my eyes have changed to the point where I am much like my camera…I have trouble focusing on close-up things.
I could try to determine wire length to blower, once I lock my daughter’s damn cat up somewhere so he won’t come climbing on me every freakin’ second!
I think picture 2 shows a circuit breaker. I remember having it replaced, as the old one looked like it was no good.
Frank, Are you SURE the '59 a/c system used a resistor? The '58 did, as shown in the 58 Manual, but I do not see one in the '59 schematic.
Wire lengths:
60"
16"
this is a “given”, comes with blower unit
24-25"
You might see from these pictures that I never completed 1) and 2).
There is also a 2-wire (green/brown) line connecting PB controls. Green goes to the blower(fan) switch, brown goes to “T” connect of blower motor. Brown should be 24", green can be 8".
I hope you make these wires up yourself, Frank. The stumbling block I had was finding connectors which would mate with existing connectors. (I never did find them).
Just went out and checked my temp control lever. Mine only says WARM with the red arrow. No Lo, Med, or Hi. Sure enough. The lever does push in and out. I must have forgotten about this function, not really needing it here in WI for warm weather driving. I must have used this in-out fan speed feature up in Maine when driving through the Maine winters in my '59. I dug out my Owner’s Manual and it shows a temp control lever like mine with only WARM and arrow, and it only says pull out for HI and push in for LOW. So I must have 2 speed. You guys must have a later version with the 3 speed.
Frank - when you’re all done with A/C, don’t forget about that little a/c decal on rear passenger side window, if they’re still available.
Side note - A/C recently went out on my Dodge Van…compressor seized. Never had good luck with A/C. To use defroster in winter, you have to unplug wire going to clutch. Kinda helps to know that.
Frank,
You may want to make the compressor clutch wire a little longer than 60", depending on the route you take to get from compressor, over the valve covers to firewall, thru firewall grommet and back to thermal switch. Perhaps 66"
Hey Fins59 and Roger,
Thank you for the continued support on this. I think what I’ll need to do is custom make my own harnesses. I should have enough spare connectors from the other '59 and a few other cars I have pulled harnesses from. I will need to purchase the correct male and female terminals to re-use the phoenolic plugs. With your measurements Roger, I should be good. Unfortunately, I will need the wire length of the blower motor. Although it is a “given” with the motor, mine is a mouse chewed uneven length of brown and green . If would be so kind as to just give me the length of the motor harness from the the point where you can see it to the T connector. You’ve already taken your car apart for the mirror issue I was having and I wouldn’t dream of asking you to remove your plenum box to check. I will have to take the motor apart and solder new wires to the blower motor. Not a big deal, I already had it apart to service the motor. As for the diagrams, the '59 Chrysler Corporation AC service manual (Full Line Up) illustrates both the two speed and three speed set ups. The 3 speed setup uses a resistor. It can not be found in the 59 PSM due to the fact it was printed before the 3 speed setup was released. The PSM illustrates the two speed. All the factory did to add the 3rd speed was to add a resistor in to further reduce the speed of the motor. I will have to “ohm out” the switch but from looking at the diagram, with the 3 speed… High is High. Medium is the two speed low. 3 speed Low is 1/2 the speed of Medium. I’m vacationing in AZ right now but when I return, I will scan copies of the Chrysler Corp sevice illustrations for everyone to see. Fins59, I do in fact have the AC sticker. If I remember correctly, it goes on the passenger rear window in the lower aft corner, correct? Thanks again for all of your help and laying on your backs to get under your dashes. Take Care,
Frank
